Abstract
Improvement of pressure drop in fixed bed reactors is obtained using catalysts or catalyst support particles which are helical lobed, polylobal extrudates having the shape of three or four strands wound helically about the axis of extrusion along the length of the particles. Catalysts are described for use in hydrotreating of petroleum distillation fractions and residues.
